  1. Model adjusted for age, sex, level of education, number of alcohol units/week, smoking status, and use of prescribed medication
  2. Due to missing values in some covariates, 682 and 231 adults and older adults, respectively, were included in the analyses
  3. Reference composition corresponds to i) 579.8 min sedentary behaviour, 193.4 min standing, 71.1 min moving, 85.5 min walking, 14.2 min HIPA, and 496.1 min in bed among adults, and ii) 589.1 min sedentary behaviour, 186.5 min standing, 72.9 min moving, 74.9 min walking, 6.9 min HIPA, and 509.7 min in bed among older adults (i.e., geometric mean)
  4. Estimates in bold indicate 95% CIs not including 0
  5. CI confidence interval, mm Hg mm of mercury, mmol/L mmol per litre, HIPA high-intensity physical activity which consists of climbing stairs (up/down), running, cycling, and rowing
